Grass was born in the Free City of Danzig (now Gdańsk, Poland). In May 1945, after service as a soldier in the Waffen SS, he was taken prisoner by U.S. forces and released in April 1946. Trained as a stonemason and sculptor, he began writing in the 1950s. In his fiction he has frequently returned to the Danzig of his childhood.

Grass attended the Danzig GymnasiumConradinum. In 1943, aged 16, he became a Luftwaffenhelfer (Air Force auxiliary), then he was conscripted into the Reichsarbeitsdienst (National Labor Service). In November 1944, shortly after his 17th birthday, he volunteered for submarine service with Nazi Germany's Kriegsmarine, "to get out of the confinement he felt as a teenager in his parents' house" which he considered stuffy Catholic lower middle class.[8][9]

However, he was not accepted by the Navy and instead was drafted in late 1944 into the 10th SS Panzer Division Frundsberg.[10][11] Grass did not reveal until 2006 that he was drafted into the Waffen-SS at that time.[12] His unit functioned as a regular Panzer Division, and he served with them from February 1945 until he was wounded on 20 April 1945. He was captured in Marienbad and sent to an American prisoner-of-war camp. Danzig was conquered by the Soviet Army and was then annexed by Poland. It renamed the city in Polish as Gdańsk and expelled surviving members of its ethnic German population. Grass found refuge in West Germany.

English-language readers probably know Grass best as the author of Die Blechtrommel (The Tin Drum), published in 1959 (and adapted as a 1979 film of the same name by director Volker Schlöndorff). It was followed in 1961 by Katz und Maus (Cat and Mouse), a novella, and in 1963 by the novel Hundejahre (Dog Years). Together these three works form what is known as the Danzig Trilogy. All three deal with the rise of Nazism and with the war experience in the unique cultural setting of Danzig and the delta of the Vistula River. Dog Years, in many respects a sequel to The Tin Drum, portrays the area's mixed ethnicities and complex historical background in lyrical prose that is highly evocative.[who?]

His Mein Jahrhundert (1999), translated as My Century (1999), was an overview of the 20th-century's many brutal historic events, conveyed in short pieces, a mosaic of expression. In 2002, Grass returned to the forefront of world literature with Im Krebsgang (Crabwalk). This novella, one of whose main characters first appeared in Cat and Mouse, was Grass's most successful work in decades. It dealt with the events of a refugee ship, full of thousands of Germans, being sunk by a Russian submarine, killing most on board. It was one of a number of works since the late 20th century that have explored Germans as victims of World War II.

Grass has for several decades been a supporter of the Social Democratic Party of Germany and its policies. He has taken part in German and international political debate on several occasions.

During Willy Brandt's chancellorship, Grass was an active supporter. Grass criticised left-wing radicals and instead argued in favour of the "snail's pace", as he put it, of democratic reform (Aus dem Tagebuch einer Schnecke). Books containing his speeches and essays have been released throughout his literary career.

In the 1980s, he became active in the peace movement and visited Calcutta for six months. A diary with drawings was published as Zunge zeigen, an allusion to Kali's tongue.

During the events leading up to the reunification of Germany in 1989–90, Grass argued for the continued separation of the two German states. He asserted that a unified Germany would necessarily resume its role as belligerent nation-state.

In 2001, Grass proposed the creation of a German-Polish museum for art lost to other countries during the War. The Hague Convention of 1907 requires the return of art that had been evacuated, stolen or seized. Unlike many countries[citation needed] that have cooperated with Germany, some countries refuse to repatriate some of the looted art.[13][14]

On 4 April 2012, Grass's poem "What Must Be Said" ("Was gesagt werden muss") was published in several European newspapers. Grass expressed his concern about the hypocrisy of German military support (the delivery of a submarine) for an Israel that might use such equipment to launch nuclear warheads against Iran, which "could wipe out the Iranian people" (dass...iranische Volk auslöschen könnte). And he hoped that many would demand "that the governments of both Iran and Israel allow an international authority free and open inspection of the nuclear potential and capability of both." In response, Israel declared him persona non grata in that country.[15][16][17]

According to Avi Primor, president of the Israel Council on Foreign Relations, Grass was the only important German cultural figure who had refused to meet with him when he served as Israeli ambassador to Germany. Primor noted:

"One explanation for [Grass'] strange behavior might be found in the fact that Grass (who despite his poem is probably not the bitter enemy of Israel that one would imagine) had certain personal difficulties with Israel." Primor said that during Grass' earlier visit to Israel, he "was confronted with the anger of an Israeli public that booed him in successive public appearances. To be sure, the Israeli protestors were not targeting Grass personally and their anger had nothing at all to do with his literature. It was the German effort to establish cultural relations with Israel to which they objected. Grass, however, did not see it that way and may well have felt personally slighted."[18]

On 26 April 2012, Grass wrote a poem criticizing European policy for the treatment of Greece in the European sovereign-debt crisis. In "Europe's Disgrace", Grass accuses Europe of condemning Greece to poverty, a country "whose mind conceived, Europe."[19][20]

Grass has received dozens of international awards; in 1999, he was awarded the highest literary honour: the Nobel Prize in Literature. The Swedish Academy noted him as a writer "whose frolicsome black fables portray the forgotten face of history".[5] His literature is commonly categorised as part of the German artistic movement known as Vergangenheitsbewältigung, roughly translated as "coming to terms with the past."

Representatives of the City of Bremen joined together to establish the Günter Grass Foundation, with the aim of establishing a centralized collection of his numerous works, especially his many personal readings, videos and films. The Günter Grass House in Lübeck houses exhibitions of his drawings and sculptures, an archive and a library.

In 2012 Grass received the award '2012 European of the Year' from the European Movement Denmark (Europabevægelsen) honoring his political debattes in European affairs.

On 12 August 2006, in an interview[12] about his forthcoming book, Peeling the Onion, Grass said that he had been a member of the Waffen-SS during World War II. Prior to that, he had been considered a typical member of the "Flakhelfer generation," one of those too young to see much fighting or to be involved with the Nazi regime beyond its youth organizations.

On 15 August 2006, the online edition of Der Spiegel, Spiegel Online, published three documents from U.S. forces dating from 1946, verifying Grass's Waffen-SS membership.[22]

In 2007, Grass published an account of his wartime experience in The New Yorker, including an attempt to "string together the circumstances that probably triggered and nourished my decision to enlist.".[23] To the BBC, Grass said in 2006:

It happened as it did to many of my age. We were in the labour service and all at once, a year later, the call-up notice lay on the table. And only when I got to Dresden did I learn it was the Waffen-SS.[24]

After 60 years, this confession comes a bit too late. I can't understand how someone who for decades set himself up as a moral authority, a rather smug one, could pull this off.[25]

As Grass has for many decades been an outspoken left-leaning critic of Germany's treatment of its Nazi past, his statement caused a great stir in the press. Rolf Hochhuth said it was "disgusting" that this same "politically correct" Grass had publicly criticized Helmut Kohl and Ronald Reagan's visit to a military cemetery at Bitburg in 1985, because it contained graves of Waffen-SS soldiers. In the same vein, the historian Michael Wolffsohn has accused Grass of hypocrisy in not earlier disclosing his SS membership.

Others have defended Grass, saying his involuntary Waffen-SS membership came very early in Grass' life, resulting from his being drafted shortly after his seventeenth birthday. They noted he has always been publicly critical of Germany's Nazi past. For example, novelist John Irving has criticised those who would dismiss the achievements of a lifetime because of a mistake made as a teenager.[26]Pat Buchanan, former White House Communications director under President Ronald Reagan, said that Reagan had planned to visit Bitburg in acknowledgement that many of the Waffen-SS were either very young or had been drafted into the Nazi forces.[27]

Grass's biographer Michael Jürgs described the controversy as resulting in "the end of a moral institution".[28]Lech Wałęsa initially criticized Grass for keeping silent about his SS membership for 60 years. He later withdrew his criticism after reading Grass' letter to the mayor of Gdańsk, saying that Grass "set the good example for the others."[29] On 14 August 2006, the ruling party of Poland, Law and Justice, called on Grass to relinquish his honorary citizenship of Gdańsk. Jacek Kurski, a 'Law and Justice' politician said, "It is unacceptable for a city where the first blood was shed, where World War II began, to have a Waffen-SS member as an honorary citizen." But, according to a 2010 poll[30][31] ordered by city's authorities, the vast majority of Gdańsk citizens did not support Kurski's position. The mayor of Gdańsk, Paweł Adamowicz, said that he opposed submitting the affair to the municipal council because it was not for the council to judge history.[32]
